| Abstract |
Alloys of Ti-47%Al and Ti-47%Al-1%Mn were oxidized isothermally and cyclically between 800 and 1000℃, and their oxidation characteristics were studied. Compared with Ti-47%Al, Ti-47%Al-1%Mn displayed better oxidation resistance at 800℃, slightly better oxidation resistance at 900℃, and worse oxidation resistance at 1000℃, though the scale adherence was better. Manganese tended to present at the lower part of the oxide scale which consisted primarily of an outer TiO_2 layer, and intermediate Al_2O_3-rich layer, and an inner mixed layer of (TiO_2+Al_2O_3). |
